Mbulelo M. worked at a gold mine for 24 years before being released in 2008 when a routine exam showed that he had TB. He is also HIV+, and TB is the biggest killer among South Africans living wtih HIV. A priest prays for him to get better at the African Gospel Church that he attends with his family. South African Gold miners are particularly vulnerable to contracting TB because of the small, poorly ventilated work conditions, high rates of TB and high rates of silicosis, a lung disease often found in miners that increases the chance of catching TB.
